This weekend I wrote an extension for Chrome/Chromium to show and/or highlight new and edited comments.

This is what the home page looks like with the extension enabled: http://i.imgur.com/LguqO.png

The comment count for a story is saved when that comments page is loaded.

With comment highlighting enabled (it is by default), comments that are new or have been edited since you last loaded the comments page will be highlighted. http://i.imgur.com/WUgkT.png

In that screenshot, the grey indicates a comment that has been edited and light blue indicates a comment that is new. These colors can be changed in the options page for this extension (accessible from chrome://extensions/)

If you have filled in your username in the options page, your threads?id=$username page will highlight and show a count of new comments visible on that page. http://i.imgur.com/Irl06.png

Edited comments will also be highlighted, but they don't show up in the count.

Thanks!
